Research Interests

 

Our research interest includes Porous Metal Organic Frameworks (MOFs) or Porous Hybrid Organic Inorganic Framework Materials and porous covalent organic frameworks (COFs) for their potential applications in:

  • Gas storage (CH4, H2 and others)
  • CO2 capture & separation (CCS)
  • Gas separations including hydrocarbon separation
  • Sensing materials
  • Heterogeneous catalysis
  • Enantioselective & small achiral molecules separation
  • Proton conducting membranes for hydrogen fuel cell. 

As far as required skills, ligands to construct MOFs and COFs, typically require a 1-5 step organic synthesis accompanied by all the standard means of small molecule characterization (1HNMR, 13C NMR, 13C SS-MAS NMR,  IR, MS, EA, TGA, UV-Vis). Hydrothermal/solvothermal reaction between ligands and metal ions produces MOFs. In addition, other crystallization techniques will be used to grow single crystals of MOFs and COFs.  MOFs and COFs are characterized by single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), synchrotron diffraction (both for tiny single crystals and polycrystalline samples) and DSC/TGA. The students will perform all aspects of the research including their own X-ray crystallography. For gas sorption and separation related studies a surface area analyzer instrument (gas sorption instrument) will be used. For proton conduction measurement an impedance analyzer will be used.
